Li Zihan said this with a sense of emptiness inside.
He had indeed approached Tang Xiaowan with an agenda, though it wasn't exactly espionage; at most, he acted as a messenger and occasionally ensured school safety.
Li Zishen had many subordinates and did not require his younger brother's intervention, but perhaps due to overprotectiveness, he always feared something might be overlooked, allowing the villain behind the scenes to take advantage.
Thus, regarding the attack on Tang Xiaowan last month in Mei Garden, Li Zishen told Li Zihan everything he knew and could share.
The purpose was simple; he wanted his brother to understand that Tang Xiaowan's situation was extremely dangerous.
However, at the beginning of school, Li Zihan had incidentally discovered that Tang Xiaowan could run extremely fast, akin to flying, and her Reflexes in dodging obstacles were also far superior to those of ordinary people, which led to his later idea of becoming her apprentice.
